Seismic response characteristics of stabilizing pile based on elastic-plastic performance

Stabilizing pile is a typical retaining structure with advantages of simple construction, convenient layout and excellent stabilizing ability, which is widely used in the landslide control project. In order to further understand the elastic-plastic performance of stabilizing pile under the action of earthquake, it is necessary to analyze the seismic response characteristics. In view of this, the numerical models were established by ANSYS and LS-DYNA, and the influence of sectional dimension, material strength and Peak Ground Motion Acceleration (PGA) on seismic response characteristics of stabilizing pile was analyzed by controlling variable method. The results show that the curve trends of displacement and equivalent stress are invariable under different design parameters. However, the values of displacement and equivalent stress both are different under each working conditions, namely, it is effective to improve the seismic ability by increasing the sectional dimension and material strength. Additionally, the results of this study can provide a reliable theoretical basis for seismic design of stabilizing pile.
